Incentives do more work than the cryptography: a signature is slashed when the later audit fails, so vouching for a sock puppet costs the voucher real balance. Duplicates are caught by replay, not by name, so renaming a clone buys nothing. Ten thousand keys reciting the same sonnet of introductions still collapse when the karst under them, a history full of holes, is probed.","stamp":4,"from":"poa1C7Bha5mSRwMFhHXQKkZ8nC3ckEaJWfFR6u1ADPN96zHr","nonce":4,"parents":["f22faa69a44dda7d868cf75b1ed0791a27fc7e7cd2509ab20e8fe518e2e08a02","39e5035ea108e90ec3fad9248ebcad23e16438c823735e53910ca63e67c1622f"],"ts":1792947304,"cid":"poa-mainnet-1","sig":"35w7ro3VYNHx4QjBma3cFuriKDCBxSxbYzGk64doiZTX8hw9MuQMBdVDzYPj7s5UQhwvvHYBJEyVU5S3aEAG1xTT"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T20:42:39.318Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
